Application and Jennifer 1922, Serial no. 530,872. Remem- March 19, i923.

T0 (JV whom it may concern; .BedtlinoWn'thzit I, YVILLTAMW. SLoANE, a citizen of the United States, residing at Chicago, in ,the jc'ounty of Cook and'State ofl'llin'ois, have invented an Improvement in Locomotives, er ,wh ichthe following is a specification. i

This invention relates to improvements in locomotives or trucks andiha s for its principal object to provide an improved construction affi ordiing'i relative flexibility of the supporting wheels and axles'so as to readilylollow uneven track. a co'p'endi'ng apdicat-i'onfor'U. S. LettersPatent, bearing gerial No. 87,376, filed July 25, 1921',-now Patent No. 1,436,205, granted-November 21, 1922, I have shown 7 and descrihed' an equalizing device for the "-pi'irpose above stated in which a flexible connection between the journal boxes on opposite ends of an axle and the'locomotive frame is provided' by means of a pair of rocking members operatively connected together by a horizontally movable tie bar or rod. In the present application, I show another form of equalizing-device in which the rocking members function in a' manner similar to that disclosed in the copending application referred to, but in which the relations of the supporting element, or journal boxes, and the supported element, or locomotive frame, are inverted with respect to each other, as will be more fully under-- stood from the following description, having reference to the accompanying drawings, in which Figure 1 is a transverse cross-sectional View of a locomotive construction in accordance with my invention.

Fig. 2 is a fragmentary view taken on line 22 of Fig. 1.

Fig. 3 is a view showing a modified form in which my invention may be embodied. i In the drawings, the embodiment of my invention illustrated in Figures 1 and 2 includes a pair of side plates 2, 2, constituting a portion of the locomotive frame, and an axle 3 having a pair of supporting wheels 4, 4, thereon and provided with journal boxes 6, 6. Said journal boxes may beef any approved construction and are arranged to move vertically between guide plates or pedestals 7, 7, of the usual construction. A

motor enclosed in a casing' o'may be suspend ed on the axle 3 in anysuitable manner'to provide motive power thereto. Referring now to the novelfe'atures c'on-' stituting my present invention, the locomotive frame is supported on iournal'boxes6, I 6, through the medium ofan'e'qualizi ngde- 6Q vice comprising a supporting member 8 extending transversely of the locomotive above the axle 3 and provided with suitable spring tical' plane transversely of the locomotive. i I I Each of said rocking members 11 has a center pivot 12 connected to the supporting member 8, a laterally extending arm 13, and and upwardly extending arm 14. The first mentioned arm 13 engages a suitable support 15 mounted on side plate 2 of the locomo-. tive frame. In the form shown, the end of arm 13 has a curved bearing portion en-' gaging the support 15 so as to permit both a rocking movement and a limited horizontal movement between the arm and support. l The upper arm 14 of the rocking member is pivotally connected to a tie bar orrod 16 extending transversely of thelocomotive and having pivotal engagement with the similar arm 14: of the rocking member 11 at the op posite side of the locomotive. Among other forms in which my invention may be embodied, have illustrated a modified form in Fig. 3*in which the arm 13 isfpivotally connected to the side plate 2 by means of a pivot pin 13' mounted in, a suitable bracket 13 secured to said plate 2. In this form the center pivot 12 is'secured 1 in a horizontally extending slot 12 .50 as I to permit relative movement of the parts during operation of the device.

In other respects, the modified form shown in Fig. 3 is similar to that shown in Figs. 1 and,2..

' In applying my'invention to a locomotive 105.

of the ordinary two-axle type, one 'suppo'rting axle is preferably mounted in the usual manner, that is to say, without an equalizing device, so asvto provide the desired stability to the locomotive body.

From the above description, it will now be clear that the construction described in the present application operates on a similar principle to that disclosed in my copending application Serial No. 487 ,37 6 above referred to, excepting that the relations of the supporting element, or journal boxes and the supported element, or the locomotive frame journalboxes. On both forms a horizontally moveable connecting rod is used to transmit the motion of one rocking member to the other, and vice-versa.

The counterpart of cross member 8 of the latter form is found in the locomotive frame of the former, as both parts mentioned provide rigidly connected supports for the center pivots of the rocking members.

The construction forming the subject matter of the present application may be used advantageously under many conditions and requirements of locomotive design.

I claim as my invention:

1. In a car, a frame, an axle, a rigid supporting member connected to opposite ends of said axle and movable vertically therewith respective to said frame, a pair of rockand interposed between said rigid member and said frame, and means operatively connecting said rocking members together.

2. In a car, a frame, an axle, a rigid supporting member connected to opposite ends of said axle and movable vertically therewith respective to said frame, a pair of rock-;

ing members at opposite sides of the frame and interposed between said rigid "member a and said frame, and transversely movable means operatively connecting said rocking members together. 1

3. In a car, a frame, an axle, a rigid sup-,

ing members at opposite sides of the frame porting member connected to opposite ends I of said axle and movable vertically therewith respective to said frame, a' pair of bell crank levers pivotally mounted adjacent opposite ends of said supporting member, each having a laterally disposed arm in'supporting engagement with the frame, and trans-- versely movablemeans operatively connect-- ing said bell. crank levers together Signed at Chicago, in the county of Cook and State of Illinois, this nineteenth day of January, 1922.
